Lead Sulfate Precipitation

Pb(NO₃)₂ + Na₂SO₄ → PbSO₄↓ + 2NaNO₃

Descripción general

Lead nitrate reacts with sodium sulfate to form a white precipitate of lead sulfate (Ksp = 2.5 × 10⁻⁸). PbSO₄ is the discharged form of lead-acid battery electrodes. The mineral form is anglesite, named after Anglesey in Wales.

Ejemplo cotidiano

When a car battery dies, both electrodes have converted to lead sulfate in a process called sulfation, which is reversed by charging.

Importancia industrial

La formación de sulfato de plomo limita la capacidad de las baterías de plomo-ácido. Comprender y prevenir la sulfatación es clave para prolongar la vida útil de las baterías y mejorar su rendimiento.
